    Abstract: A hypothermic scalp tourniquet hood comprises an exterior flexible elongated casing and interior flexible elongated casing. The two casings are joined at their bottom. The interior casing is closed at the top and the exterior casing is open to form a space in which ice can be placed. A drawstring is positioned within the hood at the bottom so that tourniquet-like pressure can be applied to the hairline of the user when the hood is in place.
